Will my TOES ever fully recover?

Hey everyone,
So I play tennis 4-5 times a week very competitively, for at least 3 hours at a time. I played in a tournament this past weekend and played 7 matches in 2 days. I wear size 15 shoes and my toes are perpetually blistered, calloused, black nails, losing nails, etc. I even have a "compounded" black nail, that seems to be layers upon layers of nail growth upon each other. I'm currently wearing Nike Vapor 9's and they are comfortable while on the court, but after a few days of hard play, my toes continue to hurt. I then take a couple days off, and repeat the cycle.
Any advice/tips to break this cycle?
Consider a pedicure? I use level 2 Thorlos and have tried creams, powders, gels, etc. Is it more about the shoe/socks/style of play. Anyone else have this problem?
thanks!

I have very narrow feet and had the same problems due to my toes ramming against the end of my shoes. I started wearing B width shoes and the problem basically went away. I also use Thorlo level 3s to take up even more room in my shoes - I swear by them as well.

The black toes happen in skiing because boots are too big. Might be worth exploring shoes that fit snugger (smaller, narrower, etc) and using an insole to reduce the movement of your foot in the shoes.

Fellow shoe size in the teens here. From my experience, it's best to go up a size, wear two pairs of socks, use socks that do not slip much, and tie your shoelaces tight when playing (so you do not slide forward).
That combination has helped me avoid blisters, blacktoe and all kinds of typical foot problems for the past decade.

My opinion is that many players do not lace the shoe strings in the front of their shoes properly. I have seen lose lower laces on some people. After they are laced up, how easy is it to slip a finger under the bottommost laces? I believe that the design of athletic shoes, using many laces, is intended to make the shoe conform to your foot while not being tight enough to bother circulation.

Try switching to socks made mostly of cotton. Thorlos are made of 100% synthetic materials so are very slippery. They can cause your foot to slide forward inside your sock and the sock to slide forward inside the shoe, both of which causes toe jamming when your stop abruptly and your toes slam into the front of your shoe. Mostly cotton socks are less slippery and lock your feet inside your shoes better when you stop.

^Yes. But watch out. There is a conspiracy afoot to discredit cotton. They will tell you cotton gives you blisters. They will tell you cotton does not breathe, and that the only thing that breathes is a petroleum product that they make for almost nothing out of refuse and sell to you at a great profit.

Cotton is on the chopping block. So stock up. I did.

I'm half kidding. Which naturally means I am half-serious. Thanks, BP for having the guts to even suggest cotton. The military~industrial~entertainment~sporting complex might come after you, though. I pray for your safety.

That said, I do like everything about VitalSocks/EuroSox. No slip. Well-made. Durable. Some cushioning. Lots of compression.

Uhm, EDIT... actually Nike sox are awesome! They did not pay me to say that. They just offered not to hurt my family.

Cotton compresses down to nothing when wet. Then there is no cushioning. Acrylic yarns like in Thorlo socks don't compress down nearly as much, providing better cushioning throughout play. But even with Thorlo's you've got to keep your laces tight. That means re-tightening your laces after your warm up, and likely at least once more during play.

A good replacement insole supports your body weight over the entire surface or the sole of the foot. It helps prevent your foot sliding in the shoe. I like Superfeet Orange because besides the support, there is an extra cushion for the balls of the feet, and the textured surface helps prevent socks from sliding.

You've got to cut your nails ridiculously short if you are a tennis player. You've got to cut them at least once a week - I inspect them more often and give them a trim as needed.

^Good point about trimming the nails.
I've heard some guys cut a little v-notch in the big toes just to keep them growing in and not out toward the sides where the flesh is.
I just cut them totally flat. The curve grows funny and could lead to ingrown nails

Cotton socks work best if they are new or like new. I bought 20 pairs of decent thick socks, costing the same as 4 pairs of Thorlo socks and only wore each pair 3 times. If you play 3 times a week, those will last at least 3 months.
No more smell, blisters, and my black toenails feel much better.
Even better if you can do what David Beckham does, never wear a pair of socks twice!

I've found that wearing a cotton sock over a synthetic give some of the benefits of both..you still have some cushioning even when your feet are wet, but they don't slide around inside the shoe like they do with a synthetic sock.

What you lose is the breathability, of course, and your feet sweat more.

Hey Tahoe, just wanted to add that I recently went through this myself and lost a toe nail. My foot was definitely banging against the front of my tennis sneaker and causing the bruising and pain. After healing, a heeded advice to get half-size larger shoes and thick Thorlo socks and, whalahhh, it worked. The shoes at times feel a little big, but I lace pretty tightly and so far haven't had any ankle problems or anything like that. I'll keep taking note to see if I stay healthy there, but so far so good. I wear wide NB tennis sneakers -- the 1187s and 1005s, with thorlo level 3s. Best of luck.
